Archive for the ‘overflow tank’ tag

I do intend to take this heap down the quarter-mile once I get it running, so I’d like to not run afoul of the tech inspectors at the track. For that reason – and because space is becoming a premium in this engine bay – I picked up this generic overflow tank at Hershey. It’s pretty much exactly the same as one of the overflow tanks that Summit Racing sells, what with the drain valve at the bottom.

I just needed to make a bracket for it out of scrap aluminum. Ron Covell, watch your back – my metalshaping skills are world renowned.

I actually probably could have squeezed the stock coolant recovery tank in its stock location right by the windshield washer fluid bottle, but my choice of location for the 4.0L computer made it just too tight, so I mounted the overflow tank there instead.

I had also considered moving the battery to the cargo area under the hatch, both for the weight distribution advantage and because I didn’t have a lot of room left under the hood – especially not for a battery. But after studying the NHRA’s rulebook for hatch-mounted batteries – which required a specific sealed battery box and a specific emergency shutdown switch – and considering the additional modifications necessary to mount the battery in the rear – remote jumper terminals, firewall pass-throughs – I simply decided to make some room under the hood, so after moving the auxiliary relay center and relocating a few other components, I freed up the stock battery location.

BTW, the alternator’s really not that close to the relays. It’s just an illusion of the snapshot.
